Description

Technical Field

[0001] The utility model relates to a quick installation mechanism for the pivot support of a toilet cover plate. Background Art

[0002] The hinge support structure of a common toilet cover plate is composed of a fixed hinge shaft assembled on the toilet cover and a support seat fixed on the ceramic toilet. The column on the support seat is inserted into the radial pin hole on the fixed hinge shaft to form the hinge support of the cover plate. A snap ring is fixed on the column. When the column is inserted into the pin hole, the snap ring is also snapped into the pin hole so that the column is elastically interference-fitted into the fixed hinge shaft. In this way, when installing or disassembling the cover plate, it is necessary to overcome the elastic force of the column passing through the snap ring and interference-fitting into the pin hole, and press down or pull up the toilet cover plate. Patents for such support hinges for toilet cover plates that use snap springs for hard plugging and unplugging include: A hinge for installing a thin toilet cover plate disclosed in the utility model (CN206852548U) applied by our company, A snap-ring type quick-release hinge disclosed in the Chinese utility model patent (CN205649458U) applied by Ningbo Bofan Sanitary Ware Co., Ltd., and A toilet cover plate hinge structure disclosed in the Chinese utility model (CN211862653U) applied by Arrow Home Group Co., Ltd.

[0003] The problems existing in the above-mentioned metal snap-ring type cover plate support shaft type disassembly and assembly hinges are as follows:

[0004] 1. When the column with the snap ring is interference-fitted into or pulled out of the pin hole, the snap ring will scrape and wear the inner wall of the pin hole, resulting in plugging and unplugging wear and jamming between the column and the pin hole, and the disassembly and assembly are not smooth. Long-term use will cause the pre-tightening force of the column inserted into the pin hole to decrease, that is, the fastening force of the cover plate hinge decreases, and it is easy to cause violent shaking of the cover plate during the opening and closing process.

[0005] 2. Since the C-shaped snap ring is clamped in the annular groove on the column, the clearance between the snap ring and the annular groove is likely to accumulate dirt, which is not easy to clean thoroughly and will breed bacteria, affecting the daily cleaning and hygienic use convenience of the toilet cover plate. Content of the Utility Model

[0006] The utility model provides a quick installation mechanism for the pivot support of a toilet cover plate, which can effectively solve the above problems.

[0007] The utility model is realized as follows:

[0008] A toilet cover pivot support quick-install mechanism, comprising a damper, a fixed hinge shaft coaxially plugged with the damper for pivoting and rotating the cover, and a column vertically mounted on a ceramic toilet support, the fixed hinge shaft radially opening a pin hole for the column to be inserted for hinged support of the cover; an elastic clamp block is fixedly provided on the side wall of the pin hole, the elastic clamp block has two elastic arm portions which are spaced apart and extend from the bottom of the fixed hinge shaft into the pin hole, and a hook portion fixedly provided on the opposite sides of the top of the two elastic arm portions; the hook portion elastically cooperates with the annular groove hook to lock the column in the pin hole, and when the column is pulled out of the pin hole, the two hook portions are stretched out of the annular groove, so that the column can smoothly detach from the pin hole.

[0009] As a further improvement, the outer peripheral wall at the top end of the column is provided with a wedging slope and a retreating wedging slope in sequence along the axial direction; when the column is inserted into the pin hole, the wedging slope presses upward and pushes open the two hook parts, and when the column is pulled out of the pin hole, the retreating wedging slope presses downward and pushes open the two hook parts to allow the column to pass smoothly.

[0010] As a further improvement, the outer peripheral wall at the top end of the column is provided with a transition annular surface between the wedging inclined surface and the retreating wedging inclined surface, and the transition annular surface is a transition surface for the hook portion to contact and slide between the wedging inclined surface and the retreating wedging inclined surface.

[0011] As a further improvement, a clearance is provided on the outer side of the pin hole of the fixed hinge shaft to allow the bullet-feeding arm to bend and deform elastically inside and outside the pin hole.

[0012] The beneficial effects of the utility model are:

[0013] The utility model is provided with an elastic clamp block on the side wall of the pin hole of the fixed hinge shaft, which can be elastically matched with the annular groove hook on the column, so that the column can be clamped and fixed in the pin hole by the elastic clamp block when it is inserted, and the elastic clamp block can be stretched out and separated from the pin hole when the column is pulled out. Compared with the traditional detachable hinge using a retaining spring, the utility model has a spring-locked cooperation between the column and the elastic clamp block, and the pre-tightening force will not change, so that the column can be inserted into or pulled out of the pin hole more smoothly, and the annular groove on the column is exposed, not easy to accumulate dirt and convenient for cleaning.

[0023] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] As Figures 1 to 7 shown, a quick installation mechanism for the pivot support of a toilet cover includes a damper 30, a fixed hinge shaft 10 coaxially inserted with the damper 30 for the cover to pivot and rotate, and an upright column 20 vertically installed on the ceramic toilet seat. The fixed hinge shaft 10 is radially provided with a pin hole 101 for the upright column 20 to be inserted to support the hinge of the cover; an elastic clamping block 11 is fixedly arranged on the side wall of the pin hole 101 of the fixed hinge shaft 10. The elastic clamping block 11 has two elastic arm portions 112 arranged at intervals and extending from the bottom of the fixed hinge shaft 10 into the pin hole 101, and a hook portion 111 fixedly arranged on the opposite sides of the tops of the two elastic arm portions 112; the hook portion 111 of the elastic clamping block 11 is elastically engaged with the annular groove 201 by hooking to lock the upright column 20 in the pin hole 101. When the upright column 20 is pulled out from the pin hole 101, the two hook portions 111 are expanded outside the annular groove 201, so that the upright column 20 can be smoothly disengaged from the pin hole 101.

[0025] It should be noted here that since the present application uses the snap-fit method of the upright column 20 and the elastic clamping block 11 for fixed installation, the pre-tightening force during its use will not change, which can make the insertion or extraction of the upright column 20 into or out of the pin hole 101 smoother. And since the elastic clamping block 11 is directly arranged on the side wall of the pin hole 101, it can effectively prevent the inner wall of the pin hole 101 from being scratched and worn by the upright column 20, causing problems such as the insertion and extraction of the upright column 20 and the pin hole 101 being stuck due to wear and jamming during disassembly and assembly.

[0026] The structures of the various components of the utility model are described below.

[0027] like Figures 1 to 4 and Figure 6 As shown, the outer peripheral wall of the top end of the column 20 is provided with a wedging inclined surface 21, a transition annular surface 22 and a retreating wedging inclined surface 23 in sequence along the axial direction; when the column 20 is inserted into the pin hole 101, the wedging inclined surface 21 presses upward and pushes open the two hook portions 111, and when the hook portions 111 slide along the wedging inclined surface 21 to the transition annular surface 22, the elastic arm portion 112 is pressed to the outside of the pin hole 101 and is elastically bent to the maximum. When the hook portion 111 passes over the transition annular surface 22, the annular groove of the column 20 201 gives way to the hook portion 111, allowing the elastic arm portion 112 to deform and reset and snap into the annular groove 201, so that the column 20 is elastically clamped and fixed in the pin hole 101 by the elastic clamp block 11; conversely, during the movement of the column 20 to be pulled out of the pin hole 101, the retreating wedge slope 23 wedges downward and spreads the two hook portions 111 and slides over the transition annular surface 22, and the hook portion 111 is separated from the column 20 through the advancing wedge slope 21, thereby achieving the smooth withdrawal of the column 20 from the pin hole 101.

[0028] like Figure 3 , Figure 4 and Figure 6 As shown, a clearance gap 102 for the elastic arm portion 112 to bend and deform is provided outside the pin hole 101 of the fixed hinge shaft 10, that is, a clearance gap 102 for the elastic arm portion 112 of the elastic clamp block 11 to bend and deform elastically is provided outside the pin hole 101 in the fixed hinge shaft 10. Since the annular groove 201 on the column 20 of the utility model is not used to install and fix the traditional C-shaped metal clip spring, the annular groove 201 is not easy to get dirty and is easy to clean.

[0029] Combine the following Figures 1 to 7 , the working principle of the utility model is described in detail, and the installation and disassembly of the column 20 and the fixed hinge shaft 10 are realized by applying the utility model.

[0030] During installation, first place the fixed hinge shaft 10 on the cover plate above the column 20 so that the pin hole 101 is radially aligned with the column 20; press the cover plate down to insert the column 20 into the pin hole 101, and the wedging slope 21 of the column 20 weds upward and pushes open the two hook portions 111. When the column 20 is inserted until the annular groove 201 thereon is aligned with the hook portion 111, the two hook portions 111 move toward each other under the action of elastic force and clamp the annular groove 201, thereby completing the quick assembly of the utility model.

[0031] During disassembly, the cover plate is pulled upwards, and the wedging slope 23 of the column 20 wedges downwards and spreads the two hook portions 111 until the hook portions 111 are completely separated from the annular groove 201 on the column 20. Then, the column 20 can be smoothly pulled out of the pin hole 101, and the column 20 can be disassembled and separated.

[0032] The above embodiments are only for illustrating the present utility model and not for limiting it. Those of ordinary skill in the art can also make various transformations or changes without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions should also fall within the scope of the present utility model and are defined by the respective claims.
